The Film: Monsters, Inc (2001)

The Moment: Chasing down evil chameleon-style villain monstoid Randall, heroes Mike and Sulley find themselves confronted with the hangar-sized chamber where the doors that the scare crew uses to enter our world are kept and collected.

What follows is an Escher-style screwball chase through several dimensions and lots of different destinations in scenes that would bankrupt most live-action productions.

In Their Own Words: “As soon as we came up with the basic concept we knew that all the doors would have to be stored somewhere,” says Pete Docter.

“And we knew we had a great third act because you get this roller-coaster ride combined with a chase around the world.

“You know, it’s kind of like Scooby Doo on steroids, with all the doors running back and forth. But really Lee (Unkrich) and the lab team took it to this whole other level that just makes it really incredible.”
